Bobbins are an economical and well-proven core design for many applications where relatively
low but stable inductance values are required.
• For higher frequency designs, use a small bobbin (Figure 1) in 43 material.
• For power applications, bobbins in 77 material are specified for A
• Bobbins in Figures 2-5 can be supplied with a uniform coating of white thermo-set plastic coating which can withstand a
• The listed dimensions are for assembled bobbins without thermo-set plastic coating.
• Bobbins are tested for A
• Bobbins 9677142089 through 9677242489 can also be purchased as tack bobbin cores. (See page 133.)
• For any bobbin requirement
Bobbins
minimum breakdown of 500Vrms. This coating will change the dimensions a maximum of 0.25mm (.010"). The last digit of
the thermo-set plastic coated part is an “8”. Bobbins in Figure 5 can be supplied with notches at one end only. This changes
the last digit of the part number to a “7”. Bobbins of this type can also be provided with a thermo-set plastic coating.
The last digit then becomes a “6”.
